I have tested with 3.2.32-rt51 and when floodpinging the latency in a kerne= l = driver(! not even usermode) was in the range of milliseconds? Have you test= ed = flood pinging with the newer kernel? = > Do you have a special reason why you want to use this prehistoric > kernel? Well, the Ti Arago project is still on this kernel? But at least they are = mainlining... Also i just tested a newer kernel on the beaglebone and it ju= st = switched itself off on booting? So would you mind sharing your kernelconfig= , = probably i was missing a driver for the power sequencer? Best regards Tim -- = ptxdist mailing list ptxdist@pengutronix.de
